Nationstar Mortgage Holdings Inc. (NYSE: NSM), today reported its net income for the second quarter of 2013 rose to $123.4 million, or $1.37 per share, compared to $62.6 million, or $0.70 per share, during the previous quarter.

The company’s second quarter results were also up from the same period in 2012, where net income was $36.3 million, or $0.41 per share.

Nationstar’s revenue grew 40% to $603.7 million in the second quarter from $431.1 million in the previous quarter. Additionally, revenue for the second quarter was also up 198% from $202.8 million reported in the same quarter in 2012.

Pro forma second quarter earnings per share (EPS) was $1.50, after adjusting for $19.4 million in platform ramp and one-time transaction expenses related to the company’s previously announced servicing acquisition from Bank of America and its acquisition of Greenlight Financial Services‘ mortgage origination business for $75 million.

Nationstar’s acquisition of the California-based Greenlight includes the company’s reverse mortgage business. The company expects Greenlight to originate in excess of $8 billion annually.

“We generated strong sequential earnings across our entire platform in the second quarter,” said Jay Bray, CEO of Nationstar. “Our platforms are strategically positioned to perform in an improving economy and we continue to see compelling opportunities in the marketplace that will deliver long-term value to our shareholders.”

Nationstar’s servicing portfolio, as measured by unpaid principal balance (UPB), ended the second quarter at $318 billion, up 2% from the prior quarter that ended with a UPB of $312 billion.

“Our servicing segment continues to make progress on our previously identified profitability initiatives which will generate increased earnings and higher margins,” said CFO David Hisey. “Our origination segment experienced a strong quarter of profitability due to record volume and our strategic focus on high margin channels.”

Looking forward, Hisey added, Nationstar remains on track to hit its full year 2013 and 2014 earnings guidance.

For the year ending December 31, 2013, Nationstar expects earnings per share in the range of $4.05 to $4.75, and EPS in the range of $6.45 to $7.50 for the year ending December 31, 2014.
